. 9 Claims. (01. 311-11) This invention relates to improvements in asurgical table. r

The principal objects of c this invention are:

First, to provide a surgical table with leg engaging braces for twistingand holding the hip bones of a patient about the axis of the bones tovarious positions convenient for X-ray of the bones. Y

Second, to provide braces for a. surgical table which will locate andhold the hip bones of a patient in any of several diverged and rotatedpositions to facilitate the surgical treatment, setting or X-ray of thepatients hip bones.

Third, to provide an appliance whichmay be easily positioned on astandard surgical table for holding the legs and hips of a patient 'inthe manner described above.

Fourth, to provide a surgical appliance for facilitating the desiredrelative positioning of a patients hip bone and an, X-ray plate.

Other objects and advantages pertaining. to the details and economies ofthe invention will be apparent from the following description andclaims. V

The drawings, of which there is on sheet, illustrate a preferred form ofmy appliance silpl ltd on a standard surgical table.

Fig. 1 is a fragmentary perspective view of a surgical table with myappliance in place theiebr'ifi Fig. 2 is a fragmentary end elevational'view of my surgical table operatively applied to the legs of a patient.

Fig. 3 is-a fragmentary cross sectional view along the line 3-3 in Fig.1.

My appliance comprises a rigid framemember I of generally U-shapedcontour havingout wardly diverging corner projections 2 at the lowertreatment. or-

as at 8, the slots extending to the bores I and screw clamps 9 areprovided for drawing the ,sides'. oftheslotstogether. I Y

Thebores 1 are arranged to receive the outv wardly diverging shaftsHlwhich may he slid in or out of the bores and rotated and clam'pedinany position in the corner. projections 2. "The outer ends of the shaftsID are securely iastened to torsion bars II which extend generallyperpendicular to the ends of the shafts ill. The tor sion bars II areprovided with outwardly offset and inwardly curved upper ends l2 andwith inwardly offset and outwardly curved hook portions l3 on'theirlower ends. The hook portions I tend curved upper portions l2 aredesirably covered by rubber or other padding sleeves J4. i f

With reference to Fig. 2, it will be noted that whenthe appliance issupported on a surgical table the angles or lower legs of a patient maybe fitted within the lower hook portions I3 with the' curved upper ends[2 of the torsion bars bear-T ing against the outside of the patientslegs adjacent to the knee joints. By rotating the lower 1 endsoi thetorsion bars outwardly, the upper ends I2 of the bars will press theknee joints of the patient slightly inwardly and resultin a twisting ofthe hip bones of the patient. By moving the torsion bars II to thedesired position'and'clarnpcorners thereof. An upper frame member 3 isspaced from the upper ends of the U-shaped frame member I and the twoframe members are covered andjoined by a top panel 4. A bottom panel 5is secured to the undersidesof the frame members I and 3 to add strengthand rigidity to the appliance. The appliance is preferably made;

the lower end of the appliance and the tablet.

ing the shafts H) in adjusted position'with'the clamping screws 9. thehip bone of the patient may be held, within limits, in any desiredposition convenient Ior'performing surgical treat-- ment or setting ofthe hip bones. Longitudinal:

tension on the hips of the patient may, of course,

be provided bypressing the shafts l0 inwardly inthe corner projections 2so that the back of the patientis lower leg engages the endof'thesurgical .table and then by lowering the head of the oper atingtable the patients own weight on the clined plane provides the traction.

Preferably, the top panel 4 of the appliance-is made of plywood or someother non-metallic ma X-ray or surgical treatment. While I haveilluslower frame member, a top panel of non-metallic trated theappliance as a separate attachment material joining said frame members,said corner for a surgical table, the shafts H3 and torsion barsprojections of said lower frame member defining H could obviously besupplied directly on the laterally diverging bores and slots openingtheresurgical table 6 if such were desired. Other to, shaft memberspositioned in said bores, minor modifications of the appliance shouldalso clamps for drawing the sides of said slots tobe obvious withoutfurther description. gether to clamp said shafts in said bores, torsionHaving thus described my invention, what I bars secured to the ends ofsaid shafts, said torclaim as new and desire to secure by Letters sionbars having inwardly facing upper leg en- Patent, is: gaging endportions above said shafts and out- 1.
